advanced by means of Google to handle the big traffic and records requirements
of its services. It is optimized for serving Google's web content and is
thought for its efficiency, pace, and sturdy infrastructure
Components of a Web Server
HTTP Daemon: The HTTP daemon, together with Apache or Nginx,
is the core factor responsible for receiving and processing HTTP requests from
customers and delivering the corresponding net content.
Server Hardware: The server hardware includes the physical
components, including processors, memory, storage gadgets, and networking
equipment, that together allow the functioning of the internet server and the
website hosting of net content.
